There's times to be real, and there's times to be phony. That's right, I said it, phony! You think I'm this nice in real life? Fuck that, son! That's just 'cause I'm on TV. I'd pull my balls out right now... skeet skeet skeet skeet!

Mankind are not held together by lies. Trust is the foundation of society. Where there is no truth, there can be no trust, and where there is no trust, there can be no society. Where there is society, there is trust, and where there is trust, there is something upon which it is supported.

Beyond a doubt truth bears the same relation to falsehood as light to darkness; and this truth is in itself so excellent that, even when it dwells on humble and lowly matters, it is still infinitely above uncertainty and lies, disguised in high and lofty discourses; because in our minds, even if lying should be their fifth element, this does not prevent that the truth of things is the chief nutriment of superior intellects, though not of wandering wits. But you who live in dreams are better pleased by the sophistical reasons and frauds of wits in great and uncertain things, than by those reasons which are certain and natural and not so far above us.

By a lie a man throws away and, as it were, annihilates his dignity as a man. A man who himself does not believe what he tells another … has even less worth than if he were a mere thing … makes himself a mere deceptive appearance of man, not man himself.

L: There are…many types of monsters in this world: Monsters who will not show themselves and who cause trouble; monsters who abduct children; monsters who devour dreams; monsters who suck blood, and... monsters who always tell lies. Lying monsters are a real nuisance. They are much more cunning than other monsters. They pose as humans even though they have no understanding of the human heart. They eat even though they've never experienced hunger. They study even though they have no interest in academics. They seek friendship even though they do not know how to love. If I were to encounter such a monster, I would likely be eaten by it. Because in truth, I am that monster.

His supposed mythomania [of Diego Rivera] is in direct relation to his tremendous imagination. That is to say, he is as much of a liar as the poets or as the children who have not yet been turned into idiots by school or mothers. I have heard him tell all kinds of lies: from the most innocent, to the most complicated stories about people whom his imagination combined in a fantastic situation or actions, always with a great sense of humor and a marvelous critical sense; but I have never heard him say a single stupid or banal lie. Lying, or playing at lying, he unmasks many people, he learns the interior mechanism of others, who are much more ingenuously liars than he, and the most curious thing about the supposed lies of Diego, is that in the long and short of it, those who are involved in the imaginary combination become angry, not because of the lie, but because of the truth contained in the lie, that always comes to the surface.

Drummond: All shine, and no substance! Bert, whenever you see something bright, shining, perfect-seeming—all gold, with purple spots—look behind the paint! And if it’s a lie—show it up for what it really is!

In the majority of cases which are brought to me as a consulting psychologist for love and marital adjustment, there are self-deceptions to be uncovered as well as attempts to deceive other people. Beneath such love conflicts there is almost always a festering psychological core of dishonesty.

My body aches from mistakes betrayed by lust
We lied to each other so much that in nothing we trust.

Trust, from the album Cryptic Writings by Megadeth, written by Dave Mustaine and Marty Friedman

Mello: The murder notebook. It's a Shinigami's notebook, and people who touch it are able to see the Shinigami.

Rester: I-impossible.

Gevanni: Who's going to believe that? A Shinigami...?

Near: [pauses] I believe him. What advantage is there for Mello in coming up with such a stupid story about a Shinigami really existing? If he were telling a lie, he would tell me a normal — more meaningful — lie. Therefore, the Shinigami exists.

False words are not only evil in themselves, but they infect the soul with evil.

Plato, Phaedes 91

Judas: I remember when this whole thing began
No talk of God then, we called you a man
And believe me, my admiration for you hasn't died.
But every word you say today
Gets twisted round some other way
And they'll hurt if they think you've lied.

Hiko Seijuro: Murder is the only art a swordsman may practice. No ornamental words can change that. You want to protect people with murder? You’ll slaughter legions so that a few may live. Many years, long before you were born, my sword was tearing asunder the lives of men. Yes, all of those men were evil, but they were human beings first and foremost, Kenshin. The world you ardently desire to enter will not know what to do with you. It will deceive you into believing that you are saving lives even as you destroy them. You will accept these lies all the while, your hands will be stained with the worst of offenses.

The silent colossal National Lie that is the support and confederate of all the tyrannies and shams and inequalities and unfairnesses that afflict the peoples—that is the one to throw bricks and sermons at.

The Book of Daniel is especially fitted to be a battle-ground between faith and unbelief. It admits of no half-way measures. It is either divine or an imposture. The writer, were he not Daniel, must have lied on a most frightful scale.
